International comparison of optical frequencies with transportable optical lattice clocks
International Clock, Oscillator Networking, Collaboration +37
Optical clocks have improved their frequency stability and estimated accuracy by more than two orders of magnitude over the best caesium microwave clocks that realise the SI second…
Optical characterisation of micro-fabricated Fresnel zone plates for atomic waveguides
Victoria A. Henderson, Matthew Y. H. Johnson, Yogeshwar B. Kale +3
We optically assess Fresnel zone plates (FZPs) that are designed to guide cold atoms. Imaging of various ring patterns produced by the FZPs gives an average RMS error in the bright…
Electromagnetically induced absorption in metastable 83Kr atoms
Y. B. Kale, V. B. Tiwari, S. R. Mishra +2
We report electromagnetically induced absorption (EIA) resonances of sub-natural linewidth (FWHM) in metastable noble gas 83Kr* atoms using degenerate two level schemes (DTLSs). Th…
Resolution of hyperfine transitions in metastable 83Kr using Electromagnetically Induced Transparency
Y. B. Kale, S. R. Mishra, V. B. Tiwari +2
Narrow linewidth signals of Electromagnetically Induced Transparency (EIT) in the metastable 83Kr have been observed for the first time. Various hyperfine transitions in 4p55s[3/2]…
Velocity selective bi-polarization spectroscopy for laser cooling of metastable Krypton atoms
Y. B. Kale, V. B. Tiwari, S. Singh +2
We report a velocity selective bi-polarization spectroscopy (VS-BPS) technique to generate a background-free, dispersion-like reference signal which is tunable over a wide range of…
